Note: The AA3000 and A3000+ were two attempts by
Commodore to build an AGA based Amiga 3000, although they were two
separate projects the designs and goals were very similar and because
neither project hit the market the boundaries between the two projects
is very blurred. It is unclear what information applies to which
project , or even if it applies to both. Therefore this page is
intended for both the AA3000 and A3000+.

The AA3000 is a very rare machine with only a handful in existence
(estimated between 3 and 6). Commodore are rumoured to have produced as
many as 50 but destroyed almost all of them around the time they went
into liquidation. Unfortunately the AA3000 was never officially
released to the public. The AA3000 and A3000+ were essentially
different projects, with similar goals. The case design was basically
the same as the A3000 case (including PSU) probably with some minor
modifications for the Zorro slots as they are aligned slightly
differently. They are about 1" closer to the case and obviously the
label on the case would be changed to reflect the machines name. This
machine is almost a hybrid between the A4000 and A3000 containing a
fully functional AGA chipset on an A3000 style motherboard with SCSI
onboard. The AA3000/A3000+ lacks the Amber chip which is found on the
A3000 for scandoubling and flickerfixing the Amiga's native display for
output to a PC style SVGA monitor. The motherboard contains space for a
planned DSP which was rumoured to provide 16bit audio and addtional
maths processing capabilities. The machine also contains a standard
200pin CPU Fast Slot for adding processor cards as found in the A3000
and A4000. The particular machine shown in the photographs is actually
used with a Commodore A3640. The machine also came with the same
Kickstart, in the same ROM format as the A4000, that is KS 3.0 on two
ROM chips. The Zorro and ISA slots were also on a daughterboard (riser
card) which is connected vertically to the motherboard. Ever fancied an
A3000 with the AGA chipset and DSP? Well try and get your hands on one
of these babies! :) This machine is reported to be very stable and runs
AGA games just as any A4000 or A1200 would.

A3000+ According to Dave Haynie

"The
Amiga 3000+ was the first computer based on the Pandora chipset (which
was later dubbed AA, then AGA). Revision 0 of this system first booted
successfully in February of 1991, thanks due to a chip revision that
got the display logic actually working. This is revision 1, which
completed the audio subsystem, and moved to surface-mount components.

As
the name suggests, this system was being designed as a drop-in
replacement for the existing Amiga 3000 motherboard. In addition to the
features everyone knows from the Amiga 3000, and from later computers
such as the Amiga 4000, the Amiga 3000+ sported the AT&T DSP3210
digital signal processor as a coprocessor.

You can see
quite a bit of support circuitry for the DSP in the upper lefthand
corner of this board. There was an audio CODEC here, designed to allow
16-bit, 2-channel recording and playback. This was very cutting edge at
the time, such chips, common today, where just becoming available. In
addition, there was a separate mono CODEC with hardware phase
correction, which supported modem protocols up to V32. The actual DSP
was located above and to the right of the CPU.

Note: this
is the real Amiga 3000+, very rare. Most of the Amiga 3000+ type
systems out, whether boards or whole computers, are actually the
scaled-down "AA3000", which was after the A3000+ had been cancelled, by
the Bill Sydnes administration, as a product." - Dave Haynie
